using associative arrays with zparseopts

I'm trying to use an associate array to parse options with zparseopts.

I have some working code, shared below, using normal arrays...but it's so awkward and verbose. i want to just ask if -f is present using opts as an associative array, by passing -A as my option to zparseopts, but I can't seem to make it work.

local -a opts
zparseopts -D -a opts f
if [[ ${opts[(ie)-f]} -le ${#opts} ]]; then
  echo "force was passed"
else
  echo "be kind"
fi

thanks for any help!

When the (i) subscript flag is used with an associative array, the substitution will return the key if a match was found, or an empty value if it was not. So you just need to test for a non-empty string:

local -A opts
zparseopts -D -A opts f
if [[ -n ${opts[(ie)-f]} ]]; then
  echo "force was passed"
else
  echo "be kind"
fi

To consolidate option parsing, I've used this (slightly cryptic) substitution:

flag=-f; force=${${:-true false}[(w)((${#opts[(i)$flag]}>0?1:2))]}
flag=-q; quiet=${${:-true false}[(w)((${#opts[(i)$flag]}>0?1:2))]}

...

if $force; then
    ...

if ! $quiet; then
    ...
